BONBON COATING MACHINE.

Application filed February 26, 1919. Serial No. 279,283.

To all whom it may concern Be it known that T, Jor r' C. HEILMA-N, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State-of Ohio, haveinvented a new and useful Improvement in Bonbon- Coating Machines, of which the following is a specification. i Myyinventiori relates ceiving a series ofcandy confections, dips ping them into a coating fluid, removing them therefrom, shaking oil the superfluous coating and depositing them upon a shelf for drying; c I

The coating fluid, which is :used for this purpose,is one which is sticky and quick to the conveyer, which carries the bon-bons during the coating, shaking and discharging operations.

Fig. 2, is a detail perspective view of the filling device and the conveyer.

Fig. 10, is perspective view of the means for: inverting the conve or, and of the mechanism for removing the bon-bons from the inverted conveyer. 1

Fig. 11, is a detail view of the mechanism for moving the rake which assists in removing the bon-bons from the conveyer.

My machine comprises a hon-hon receptacle A, in which the attendant deposits the bon-bons a, which are to be coated, a conveyer B, which receives the bon-bons from the receptacle, a trough C which conveys the coating material and which is carried upward around the bo-n-bons in the conveyor and is then. lowered, a. shaking device D, for shaking the superfluous coating -material from the bon-bons, a device E for inverting the conveyer and a rake E for removing the The receptacle for receivin'g'the bon -bons consistsof an open top box whichis divided into a series of pockets or receptacles a.

The receptacle has a movable bottom a eX- tending beyond the rear wall of the receptacle and which is securedfat one side to arms ai which are pivoted to the ends of the upon one end of an arm a the other end of which arm is secured to the end wall, of the tank F, which holds the liquid coating mate rial. The arm a may be made of a resilient or spring material adapted to yieldingly permit vertical reciprocation of the receptacle A, or the arm a may be provided with a longitudinal slot accommodating the pivotal connection between itself and the receptacle, and in which the pivot may slide as the receptacle is reciprocated. Any

other suitable means to accomplish this by gear wheels a -a with the main drive shaft G, which may receive its rotation from any suitable source of power. In the presreceptacle, and which are likewise pivoted ent instance the drive shaft is shown driven by a chain of gears g, g, g 9 from an electric motor, not shown. At their upper end shafts a have rearwardly projecting arms a, a, which have stretched between their ends wires a, a, which are in vertical alignment with trough C, and are adapted to be brought to bear down upon the bon-bons in the baskets during the coating operation, by the action of cam a and coiled spring a.

Conveyer rod B, has mounted upon it a series of wire baskets b, by means of a series of longitudinal wires 6, which hold the baskets: in vertical alignment with the pockets in the receptacle A,.when the conveyer is at the forward limit of its travel.

Rod B is mounted at the upper ends of arms 6 b the lower ends of which are pivoted upon a rod 6 which is secured between the side walls and beneath the bottom of tank F. Arm 6 carried a pin 6 which fits into a groove inthe cam Z which is mounted upon one end of drive shaft G, which has upon its opposite ends mutilated. gear 9*, which meshes with mutilated gear 9 upon a studshaft upon which the gear wheel g is secured. The stud shaft 9 is journalled in one of theside walls of the tank. The trough G has in one side a series of slots 0, which come in alignment with the arms I) which support the wire frames, so thatwhen the trough is raised the frames carrying the bon-bons may enterit. Trough G is supportedby and arms 0', upon rod 0 which is secured at its-ends to ver tical rod-s c 0 Rods c 0 are pivoted at their lower ends to links 0 c, which at their other ends are pivoted upon rod 0" which. is supported by tank VF. Arm 0 has secured to it an arm 0 which carries at its outer end a roller 0", which contacts with a cam 0 which is mounted upon a shaft C which is connected by gear wheels o 0 with a gear wheel'g upon drive shaft G.

The shaking mechanism comprises a lever D, which is: fulcrumed upon. a bracket d which is mounted upon a standardd which is secured at the side of the tank. At its upper end there is a coiled spring (Z which is secured between the upper ends of the standard cl. and the lever D. The lower end of the'lever D is in the path of a series of knobs g which project from the outer face of the gear wheel 9 The upper end of the lever D, is in the path of the end of rod B, which has a limited transverse movement in the rods 6 6 by means of collars b [2 which are secured upon the rod B. Between collar 6 and arm 6 is a coiled spring b", which-normally holds collar 6 in contact with armb so that the end of the rod B is in the end of the path of the lever D.

The mutilated parts of the gears g are disposed so that they register, just as the knobs 9 upon the gear wheel come in contact with the lever D, and the rod B contacts with the lever B.

The meansfor inverting the frames 6 for discharging the bon-bons therefrom is as follows z-Rod B, has secured upon one of its ends a gear wheel in whose path a rack E is mounted upon the side of the tank F. RakeiE for removing the bon-bons from the inverted baskets has fingers e which register with the baskets, and a handle a which is mounted reciprocally in bracket 6 secured to the rear end of the tank F. Its lower end carries a roller 6 which contacts with the cam 6 upon a shaft E which carries bevel gear e which'meshes with a bevel gear 6 which is secured upon the drive shaft G. The came is positioned upon itsshaft FF so that the rake is'lowered upon the bonbone after the baskets have been inverted Guide wheel 6 has seupon the shelf F. cured toit a guide rod '6 having a finger 6 which upon the return movement of the conveyer enters the guide way a in the guide, which is mounted upon the side of the tank, the functionof the guide rod finger and the guide way being to steady the conveyer shaft B, so as to hold the baskets 7), inhorizontal positions. The guide X consists of two parallel or slightly curved concentric plates X and a bracket X extending from the tank F and forming a way 6 between them. The. finger 0 is adapted to enter the way a".

In operation the attendant fills the pockets of the receptacle A with bon-bons to be coated, whilst the preceding lot of bon-bons is being'carried. by the conveyer through the operations of dipping, shaking and depositing upon the shelf. Upon the return of the conveyer to the position shown in full line inFig. .1, the receptacle A is loweredby action of the spring a uponv the rod a, to the position shown in dotted line in Fig. 2, and the bottom 0. of the pockets being open, as shown in. dotted line in Fig. 3, when the receptacle A is moved downward. by the act-ion of cam a and spring a", the arm a turns upon the pivot by which it is affixed to arm a thereby moving the bottom a backward and away from the receptacle A, to the position shown in Fig. 3, in dotted lines, and the bon-bons drop on to the baskets Z), andby movement of the cam a against the roller a recepta cle A is moved to its uppermost position.

The groove in the cam 19 then advances the conveyer to the first of the positions indicated by dotted linesshown in F ig. 1. The cams a then lower the arms a so as to cause wires-n a, to bear; upon the honbons, and the trough G is carried upward by the arms 0 0 so asto cause the trough to surround the baskets holding the bonbons..

2 supported by i the wires a fla are necessary to hold the the pin 6 is passing through a circular part of the groove, the center of the circle being shaft G, so that the conveyer is sta tionary. The trough is then'lowered by action of the springa and the'cams a and the conveyer is advanced to the second posi tion as shown in dotted linein Fig. 1,

In this second position the end of rod B is brought in contact with the lever D, and the mutilated parts of the gear wheels g, g, register so that the drive shaft G becomes stationary and the conveyer is held stationary. The rotation of the gear wheel 9 then causes the knobs g to impart a transverse rapid vibration to the rod B, so that any superfluous fluid upon the bon-bons is shaken off intothe tank F. Then the gear teeth of the gear wheels g, 9 coming into mesh, the conveyer, is carried to the third position indicated b dotted lines in Fig. 1, wherein the gear w eel 6 upon the rod B, engages rack E, which rotates the rod B and inverts the baskets 5 upon the shelf F. Rake E is then lowered upon the bon-bons, which are left upon the shelf when the conveyer is returned to its forward position by the action of the cam Z2 What I claim is 1.
